Massachusetts Senate President Stan Rosenberg said one possible change to the state's marijuana law could involve who oversees the regulation of pot sales.
Voters last year passed a legalization ballot question, which gave control of the Cannabis Control Board to the state treasurer.
Rosenberg told Boston Herald Radio, that ultimately, any changes are up to a legislative committee reviewing the law.
"It's a fair question to raise and ask," Rosenberg said. "Is this the right structure that was in the bill? But the treasurer's office, they have so much knowledge and so much capacity here, I can't imagine they won't be playing a role in this."
House Speaker Robert DeLeo has also questioned who will end up overseeing the control board.
State Treasurer Deborah Goldberg said deadlines mentioned in the law won't be met if her office is not the one in charge
